STATUS 9
Vehicle speed monitoring
Status ET415 changes to STATUS 9 if the vehicle speed received by the computer is
invalid or absent.
This signal is conveyed on the multiplex line and deactivates the cruise control.
Carry out a multiplex network test, then Perform fault finding on the ABS computer.
Deal with any present or stored faults (see 38C, Anti-lock braking system,
interpretation of faults).
Reinitialise status ET415 on the injection computer by running command RZ007
"Fault memory".
If status 9 continues, contact the Techline.
STATUS 10Monitoring by injection computer
Status ET415 becomes "STATUS 10" when driving with cruise control active (ET042
"Cruise control/speed limiter": CRUISE CONTROL) if the injection computer detects
a fault anywhere in the engine management system, or an engine speed that is too high
or too low.
This signal is conveyed on the multiplex line and deactivates the cruise control.
Carry out a multiplex network test, then Perform fault finding on the injection computer.
Deal with present or stored faults.
Reinitialise status ET415 on the injection computer by running command RZ007
"Fault memory".
If status 10 continues, contact the Techline.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

Switch the ignition on and check for faults.
Check the engine battery voltage with the engine switched off and the engine running.
If no faults are present or stored, restart the vehicle and test at idle speed.
Do not accelerate too much and reach an engine speed that is too high.
STATUS 3, 14, 16Accelerate above idle speed for a few seconds.
STATUS 2Check that the clutch pedal (ET405 "Clutch pedal switch") is not pressed and that the
vehicle has stopped completely.
STATUS 4, 17Test the present and stored faults and repair.
STATUS 8Reset the EGR offsets by referring to the interpretation of command SC036
"Reinitialise programming" and select "EGR valve".

CRUISE CONTROL/SPEED LIMITER BUTTONS
NOTESSpecial notes:
Carry out these checks if the statuses do not correspond with system operation
programming.
INACTIVE
Status ET703 becomes INACTIVE when none of the cruise control/speed limiter
buttons are pressed. These buttons are located on the steering wheel.
To carry out the checks and measurements in complete safety, follow the instructions
for removing the driver's front airbag (see MR 364 (Mégane II), 372 (Scénic II) or 395
(Laguna II), Mechanical, 88C, Airbag and pretensioners, Driver's front airbag,
removal-refitting).
If status ET703 does not display INACTIVE,
– check the condition of the cruise control/speed limiter +/- button and the condition of
its connector.
– check the condition of the cruise control/speed limiter R/0 button and the condition of
its connector.
Repair if necessary.
INCREASEStatus ET703 becomes PLUS when the cruise control/speed limiter + button is pressed.
This button is on the steering wheel, on the left-hand side.
If status ET703 does not display PLUS, check the condition of the cruise control/speed
limiter +/- button, and the condition of its connector. Repair if necessary.
To carry out the checks and measurements in complete safety, follow the instructions
for removing the driver's front airbag (see MR 364 (Mégane II), 372 (Scénic II) or 395
(Laguna II), Mechanical, 88C, Airbag and pretensioners, Driver's front airbag,
removal-refitting).
Measure the resistance of the following connections while pressing the "+" button
(on the button tracks):
– Connection code86G, of component 331.
– Connection code 86M of component 331.
If the resistance is not approximately 300 Ω, check the continuity of the connection
when the button is not pressed.
If there is continuity, replace the +/- control button.
If there is a repair procedure (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.

Only perform these tests if the parameters do not correspond with the system
operation programming.
These statuses should only be interpreted if DF312 "Speed request" is present or

This status shows the stored engine status during a regeneration failure when driving:
NONE, + AFTER IGNITION, RUNNING, STOPPED.
Each STATUS between ET706 and ET715 corresponds to regeneration failures for which the mileage is recorded
from PR794 Stored regeneration failure no. 1 to PR803 Stored regeneration failure no. 10 (for example,
PR797 Stored regeneration failure no. 4 is related to ET709 Stored engine status no. 4).
